This study investigated the microstructure of the dissimilar metal welding of Inconel 625 and AISI 316L using Continuous Current Gas Tungsten Arc Welding (CCGTAW) and Pulsed Current Gas Tungsten . Primary water stress corrosion cracking is most likely to grow as the roots crack at the bottom of a weldment [25,26] so a flat bottom hole having a diameter of 5 mm and a notch of 0.5 mm × 5 mm × 5 mm were machined at the boundary between the weld-metal part and buttering layer of the specimen. This boundary is an area where PWSCC is formed .
When designing piping systems for various industrial facilities, carbon steel and stainless steel are widely being used. In order to satisfy design requirements in the piping systems, the two different materials are often welded in various cases. Therefore, for quality assurance, it is necessary to understand mechanical and metallurgical properties of dissimilar . Use the suitable filler material: Using the appropriate filler material is crucial, depending on the type of Inconel you are welding. For instance, Inconel 625 is the filler material when welding Inconel 718. Control heat input: Inconel retains heat longer than other materials, which can lead to warping or cracking. Therefore, controlling the .

hardness than the base metal and weld metal zones, with carbide clusters at grain boundaries. Prabu et al. [11] studied the hot corrosion characteristics of Inconel 625 joints using PCGTAW. It is found that ERNiCrMo-4 filler showed marginally greater strength than ERNiCrCoMo-1, but cracks were observed in the base metal. 16 Common Types of Weld Defects. In sheet metal fabrication, improper welding can lead to several defects. This overview covers common issues, their causes, and remedies to ensure quality and durability. . This is .

Fall 2008 Examination Findings JA Fitzpatrick Flaw . • Fabrication related defect at RPV nozzle cladding to This research paper aims to optimize the TIG welding parameters to join dissimilar metals of AA5083 and AA7075 using the Taguchi technique. The TIG welding current and root gap of butt geometry . Cracks were oriented in and along the weld. Base metals, Inconel 718, and Nimonic 80A differ in yield strength but have the same modulus of elasticity. Electron beam welding was used to butt weld Inconel 718 to Nimonic 80A. J resistance curve (J vs. crack extension) was experimentally found to determine the elastic–plastic fracture toughness .In this study, dissimilar butt joints were formed between as-rolled Inconel 718 and SUS 316 using cold metal transfer (CMT) with ERNiFeCr-2 filler metal at a welding speed of 5 mm s −1 and three different welding currents (130, 160 and 190 A). The morphology, microstructure, and mechanical properties of the joints and the mechanism by which the joint interface formed were studied.
